Fig. 4 shows a tapered operating member 25" which, instead of having afrustoconical face, has a helical face, the convolutions 26 of whichgradually increase in diameter from The indicator 18 bears on thishelical face which exerts a displacing pressure in a direction at aright angle to the axis of the valve stem, so that there is lessfrictional resistance to has a frusto-conical face, and exerts a diskplacing pressurev in a direction oblique to I find, however, that theelongated bearing of the hub 21 on thestud 22 reduces the bindingpressure of the hub on the smaller to the larger end.

When the construction is such that the valve stem, in performing itsfunctions, is

rotated Without moving lengthwise, as in gate and plug valves, anoperating member .25 such as that shown by Fig. 5, may be 100. the studto a negligible minimum, when the stem 15 while rotating therewith, thestem being provided with a key'or feather .engaging a groove inthe'member 25". Said member is therefore adapted to be moved lengthwiseconjointly bythe rotation of the a stem, and. the engagement of theindicator, 18

with the groove 27, the edge 28 of the in dicator being the equivalentof anfinternal 1 screw-thread and the groove 27 being the equivalent ofan external screw-thread, so

that the rotationof the stem without longis tudinal movement, rotatesand causes a longitudinal movement of the member 25".

The scale 20 may be supported by any suitable means, such as an arm 32,having a hub 33 bearing on a seat 34 on-the casing,

as shownby-Fig. 3, said hub being clamped between the casing and thebonnet 17, and

prevented from turning by a dowel-pin 35. Any. other'suitable fixedindicating member or;device adapted to cooperate with the l Iinovableindicator may be substituted for 'qthe scale 20,. and if desired, themovable indicator may be used independently of any fixed indicatingmember.

My invention is distinguished by the fact thatprovision, is madeforregistering ex-r."
